Background. In an attempt to decrease the toxic effects of fluorouracil, doxorubicin, and methotrexate (FAMTX) by reducing the dose of methotrexate from 1500 mg/m2, according to the original regimen, to 1000 mg/m2, the authors designed the modified FAMTX treatment that was evaluated in a prospective Phase II‐III randomized trial. Methods. Patients with advanced gastric cancer were randomized to receive modified FAMTX treatment or supportive measures only (control group). In the middle of the study, the randomization was interrupted because of strong evidence of benefit in terms of tumor reduction and projected survival in the treatment arm receiving chemotherapy. By the end of the study, 30 assessable patients had received chemotherapy and 10 had received supportive treatment. Results. The overall response rate was 50% (15 patients); 12 patients (40%) had partial responses and 3 (10%) had complete responses (CR). One patient with extensive peritoneal carcinomatosis attained a CR pathologically documented by laparoscopic examination and peritoneal biopsy. The median overall survival time of the treated group was 9 months, whereas that of the control group was only 3 months (P = 0.001). The median overall survival time of the responders was 16 months, and their median remission duration was 8 months. The regimen was well tolerated, with a very acceptable toxicity profile. There was one toxic death resulting from neutropenia and sepsis in a patient who did not receive adequate leucovorin rescue. Conclusions. This regimen appears to prolong survival in patients with advanced gastric cancer, and the reduction of the methotrexate dose does not seem to compromise its efficacy. Cancer 1993; 72:37–41.

Background: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated. Aim: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition. Methods: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers “fully agree” and “partially agree” was reached. This article presents only the responses of the participating experts. Comments on each statement, as well as a literature review, will be presented in future publications. Results: Of the 67 statements, there was consensus in 50 (74%). In 10 declarations, there was 100% agreement. Conclusion: The gastric cancer treatment has evolved considerably in recent years. This consensus gathers consolidated principles in the last decades, new knowledge acquired recently, as well as promising perspectives on the management of this disease.

Investigators have speculated on the role of Helicobacter pylori in gastric carcinogenesis. The current study was performed to evaluate prospectively the prevalence of H. pylori infection in the stomachs of Brazilian patients with gastric carcinoma. Forty patients receiving gastrectomy for gastric carcinoma were studied. H. pylori was examined in four areas without atrophy or with minor atrophic changes. Mucosal fragments were obtained for microbiologic studies in 19 cases. H. pylori was detected in 82.5% of the cases. Of the cases evaluated by histologic and microbiologic methods, 94% had positive results by at least one method. In most cases there were small numbers of microorganisms. There was no correlation between the site and histologic type of neoplasia and the presence of H. pylori. The use of more than one diagnostic method improves H. pylori detection in gastric carcinoma. The small number of microorganisms observed in gastric carcinoma cases may lead to an underestimate of H. pylori in histologic sections. This might explain the variation in H. pylori infection rates reported for patients with gastric carcinoma.

Background : The II Brazilian Consensus on Gastric Cancer of the Brazilian Gastric Cancer Association BGCA (Part 1) was recently published. On this occasion, countless specialists working in the treatment of this disease expressed their opinion in the face of the statements presented. Aim : To present the BGCA Guidelines (Part 2) regarding indications for surgical treatment, operative techniques, extension of resection and multimodal treatment. Methods: To formulate these guidelines, the authors carried out an extensive and current review regarding each declaration present in the II Consensus, using the Medline/PubMed, Cochrane Library and SciELO databases initially with the following descriptors: gastric cancer, gastrectomy, lymphadenectomy, multimodal treatment. In addition, each statement was classified according to the level of evidence and degree of recommendation. Results : Of the 43 statements present in this study, 11 (25,6%) were classified with level of evidence A, 20 (46,5%) B and 12 (27,9%) C. Regarding the degree of recommendation, 18 (41,9%) statements obtained grade of recommendation 1, 14 (32,6%) 2a, 10 (23,3%) 2b e one (2,3%) 3. Conclusion : The guidelines complement of the guidelines presented here allows surgeons and oncologists who work to combat gastric cancer to offer the best possible treatment, according to the local conditions available.

ResumoAneurismas isolados da artéria ilíaca interna são raros, acometem 0,1% da população e correspondem a 1% dos aneurismas aorto-ilíacos. Na maioria das vezes, os pacientes são assintomáticos, mas podem apresentar dor abdominal, massa pulsátil no hipogástrio ou na fossa ilíaca, sintomas compressivos urinários, gastrointestinais ou neurológicos. Podem ocasionar quadro de abdome agudo, principalmente quando há ruptura. O diagnóstico precoce dos aneurismas isolados de artéria ilíaca interna é incomum, sendo identificados quando mais volumosos ou rotos, o que aumenta significativamente sua morbimortalidade e torna seu prognóstico mais reservado. Dessa forma, representam um desafio terapêutico. A ligadura cirúrgica tem sido o tratamento mais comum, entretanto a cirurgia endovascular tem mostrado bons resultados, inclusive nos aneurismas rotos. É relatado caso de aneurisma de artéria ilíaca interna isolado roto diagnosticado durante laparotomia para abordagem de abdome agudo. Palavras-chave:Aneurisma roto, artéria ilíaca, abdome agudo. AbstractIsolated internal iliac artery aneurysms are rare. They affect 0.1% of the population, and account for 1% of aortoiliac aneurysms. Patients are mostly asymptomatic, yet they can have abdominal pain, pulsatile mass in the hypogastrium or iliac fossa, or urinary, gastrointestinal or neurological compressive symptoms. Such aneurysms are likely to course with an acute abdomen, especially when ruptured. Early diagnosis of isolated internal iliac artery aneurysms is difficult, as they are more easily detected when larger or ruptured, which significantly raises their morbidity and mortality rate and determines a poor prognosis. Therefore, they are a therapeutic challenge. Surgical ligation has been the most common treatment; however, the endovascular approach has presented good outcomes, even in the event of ruptured aneurysms. A case of ruptured isolated iliac artery aneurysm diagnosed during a laparotomy (acute abdomen approach) is reported.Keywords: Ruptured aneurysm, iliac artery, acute abdomen. IntroduçãoO aneurisma isolado da artéria ilíaca interna é condição incomum, grave e de difícil diagnóstico. Acomete cerca de 0,1% da população em geral e corresponde a aproximadamente 1% dos aneurismas aorto-ilíacos [1][2][3] , sendo a artéria ilíaca comum a mais envolvida (85%), seguida da artéria ilíaca interna (10%) e artéria ilíaca externa (1%) 4 . Esse tipo de aneurisma é mais frequente em homens e idosos (média de 69 anos) [2][3][4] . Cerca de 50% são bilaterais 5 .Na maioria das vezes é assintomático, encontrando-se frequentemente roto nos quadros manifestos 6 . Quando sintomático, os sinais e sintomas dependem do tamanho, localização e relação com estruturas adjacentes. Relato de casoPaciente do sexo masculino, 67 anos, com quadro súbito de dor abdominal, referida em região lombar e em fossa ilíaca direita, associada à disúria e constipação
